Roles of Gallium-67 scintigraphy, ultrasonography, and computed tomography in the detection of abdominal abscesses

Journal Article · · Semin. Nucl. Med.; (United States)

The evaluation of patients with suspected abdominal abscesses begins with a history and careful physical examination. Gallium-67 (/sup 67/Ga) scintigraphy, ultrasonography (US), and computed tomography (CT) are utilized only after other routine investigations have failed to localize the abscess. All three modalities are reliable for the detection of abdominal abscesses. The decision regarding which of these three diagnostic tests to use in a particular patient rests upon clinical considerations. If the patient has acute localizing signs and symptoms, /sup 67/Ga should not be used initially. In this type of patient, rapid diagnosis is best provided by either US or CT. Further radiologic investigation may be terminated if the CT or US findings are characteristic of an abscess. A /sup 67/Ga scan should be performed in a patient with acute localizing signs and symptoms if the initial CT or US is negative. In a patient with nonlocalizing signs and symptoms, /sup 67/Ga imaging should be employed as the first procedure since the entire body is easily surveyed. If the /sup 67/Ga images are abnormal, then CT or US should be utilized for further lesion characterization. This diagostic approach will optimize the rapidity of patient evaluation and will minimize diagnostic errors.
